摘要	The mechanism of photoluminescence (PL) quenched and lifetime enhanced by semiconductor nanoparticles (SNPs)-metal nanoparticles (MNPs) couple were investigated and the experimental results have been described and analyzed by the conventional Foster resonance energy transfer (FRET). The plasmonically coupled SNPs have demonstrated the PL quenched obviously and lifetime enhanced from 17.7 ns to 30.8 ns, near to 2 times. The hybrid colloidal CsPbBr3perovskite SNPs/Pt MNPs (S-M) structures exhibit novel optical properties due to the synergetic interaction between the individual components. In hybrid S-M nanostructures, colloidal chemistry incorporates SNP and MNP into a single unit resulting in the formation of plexciton (or excimon) which has now been established in a series of hybrid structures. The experimental results of femtosecond transient absorption (TA) spectroscopy based on the time-resolved pump-probe confirm the transformation from excitons to plexcitons. It was found that the experimental data can't be well described by the theory based on conventional FRET. To modify and improve the conventional FRET is needed. 2017, Science Press.
